Description

Film-forming agent suitable for use as a cosmetic and Process for its production The invention relates first of all to a use Film-forming agent suitable as a cosmetic, in particular a cosmetic face mask.

There are already various cosmetic products to be applied to Skin known for its beauty and cleansing. Urter these are special Clays dispersed in water and known in cosmetics as T @ npackages at the most common as it has been shown to cause uncomfortable excess cle and absorb keratinized parts of the outer epidermis. If you wear these clays in wet Condition on the skin and allow it to become dry on the skin, then become the case subsequent removal of the clays also removes these unpleasant clefts and skin parts.

Also, these cause clays when applied as a face mask when drying on the face, for example, cause the skin to shrink and produce thus a tightening effect, which leads to a reduction in wrinkles and to a Leads to improvement of skin tension.

So far these clays have been used to produce additional effects Ingredients such as B. Astringents, Coolants, Rubefacientia and @leichende Agent added. Such clay suspensions, which are available in various forms, are among the most common face masks today.

'. : enn also such "items on sound basis especially nowadays are common, they have the N? chu share that they are difficult, arduous and are uncomfortable to apply, dry slowly and are even more uncomfortable to remove are. Attempts to avoid these undesirable properties have resulted in many Means invented as a substitute. So it has been shown, for example, that # ~ soluble Rubber films tighten the skin and give it elasticity.

However, these films have no buying and cleaning properties and are difficult to remove. On the other hand, alginate gels have a good cleaning effect, However, they do not give the skin elasticity. It has become common with latex films shown to be too irritating to the skin because they are highly alkaline also do not have the ability to restore elasticity to the skin.

Films made from a mixture of latex and alginate are sometimes irritating. ar not however, they lack the ability to snatch the skin.

Currently available @csmetic tables suitable for use as a face mask Remedies are unsatisfactory not only because of their effects on the skin Requirements not met, but also because of the work wall that is used to manufacture the means, their impact on the skin and for the removal of the dried material is required. Some of these remedies are specially made using such ingredients which must be applied immediately after mixing to be effective to be- Gie must therefore by the consumer himself, and zw @@ directly before the application onto the skin.

Obviously, this can be an undesirable task.

Other funds currently available require removing d-r Skin is a tedious process after it has dried, as it, if at all, have only a very low tensile strength and are therefore removed piece by piece m³ have to.

The object on which the invention is based is therefore to provide a Means and a method for producing this method to be determined, which is described in Ready-to-use form is available, easily applied and reapplied can be removed and the skin rejuvenated and taut O The invention consists in that it consists of an essentially aqueous, homogeneous, film-forming rubber, a fibrous material, water and alcohol containing mixture. Of the Film-forming gums can have the consistency of a cream or psste and that fibrous material, e.g. B. Oellulosematerial, gives the agent a firmness, for that? the mask easily and quickly peeled off the sound in green sections or can advertise deducted.

In addition, the composition containing the rubber and the fiber material be provided with certain lubricants and release agents in order to reduce the tendency of the The film or agent adheres so firmly to the skin that it is difficult to remove will decrease. These funds also contribute to make sure proper dispersion of the fibrous material in the rubber so that the means according to the invention is pleasantly pliable and easily adheres to the @eut.

The means according to the invention can be given to the consumer in a form be supplied in which it can be applied to the body without sufficient because # this requires special expertise. The agent troc7. net quickly forming a film.

In addition, the invention can be used for a face mask be mixed with other additives, so that when applied to the skin, different, effects desired by the consumer can be achieved.

Such additives to increase the cosmetic effect of the are z. B. Humectants and Cl containing materials, Rubefacientia or other stimulant For the skin as well as the skin whitening, cleansing or depilatory agents.

The different types of rubber used to form the composition of the invention used "." earths contain one of the various natural or synthetic Hydrocolloids, which have thickening and stiffening properties and which are responsible for * formation one pasty film from an aqueous dispersion are capable. Suitable Gunriarten are z. N ethyl and hydroxypropyl cellulose ethers, e.g. B. under trade names such as Methocel 60 HG 4000 and Methocel 65 HG 50 from Dow Chemical Company placed on the market; Sodium carboxymethyl cellulose, gum arabic and tragacanth and the different types of cerrage gum. The rubber is in one suitable, preferably denatured ethyl alcohol dispersed, so z. B. in ethyl alcohol with the designation 3D 40 Alcohol, the t-butyl alcohol as the primary denaturant contains and also a suitable substance, such as B. brucine sulfate, quassin or Bitrex, which gives the alcohol an unmistakably bitter taste, so that the consumer is warned against accidental ingestion.

Such fiber materials can be used for reinforcement for the agent according to the invention can be used, which can be mixed smoothly with the hydrocolloids. Wood pulp of medium fiber length has in this view z. B. as very satisfactory proven.

So that the mask that has dried on the skin can be removed more easily can, can: 'as the means of which the l'astre consists, non ionic, õthoxylated, surface-active substances contain «These substances do not reduce only the ability of the means to adhere to the skin9 but also make it smoother and easier to apply.

Thoxylated, long chain fatty alcohols and fatty acids are for this Purpose beneficial. Suitable athoxylated fatty alcohols (/ ter) are z. B. an under the name Lantrol A ',' I'S from Malstrom Chemical Corp. produced ethoxylated Lanolin alcohol; BriJ j 58 manufactured by Atlas Chemical Industries inc .; Solulan 16 manufactured by American Cholesterol Products Inca and Lipal 15 CSA from Drew Chemical Corp .. Suitable athoxylated fatty acids (esters) are, for example Polyoxyethylene (40 mol) stearate, which is available under the name MyriJ 52 from Atlas Chemical Industries Inc. is manufactured. Polyoxyethylene 600 monostearate made by Kessler Chemical Company, Inc.; Lipal 4 S, manufactured by the Drew Che-ical Company Inc. and Solulan 98, manufactured by American Cholesterol Products, Inco The invention also relates to a method for producing the invention Means. According to the invention, the method consists in that the gum contains the alcohol is added, mixing vigorously until the gumni is in the alcohol Completely is dispersed, since # the fiber force atriall entered with stirring in water vrird, stirring until the fibrous material is dispersed therein is that this dispersion is added to the dispersion containing the alcohol and the rubber and all components d. it "by means of being mixed with one another, until the mixture is homogeneous and smooth.

The inventive method has the advantage that both the rubber as well as the fibrous material are present in the form of a dispersion before mixing. As a result, a uniform "ischunr" is achieved. The mixing time and also that for mixing required energy expenditure can be kept short or low. Also swells the gum on much more evenly if it was already on before coming into contact with water is in finely divided form.

In one embodiment of the method according to the invention, the the dispersion containing the alcohol and the gu-mi first. until a smooth transparent gel is obtained. Fit this gel is then the dat aqueous dispersion containing fibrous material mixed.

In one embodiment of the invention, in the water first a surface-active agent is dissolved before the fibrous material is introduced will.

The fibrous material is used in one embodiment of the invention in the form of a slurry containing preferably about 25 percent by weight solids supplied.

To increase the cosmetic effect of the agent you can use the wet before the fibrous material is added to which additives are added. Even Additives can also be added to alcohol. So is the alcohol in one type of execution the invention added a perfume before dispersing the Gu-Tis.

The following are representative, specific examples of the invention Means and listed for the mixing process for its preparation: Example 1 Ingredient Percentage by weight Part 1 SD40 Alcohol 30. 0 Methyl and hydropropyl cellulose ethers (Methocel 60 HG 40 # C) 3.0 part 2 water 40.0 part 3 wet 23.0 ethoxylated lanolin alcohol (Lantrol AWS) 1.0 paper pulp 3. 0 100. 0 Part 1 becomes through it manufactured so that the gum is mixed with the alcohol by rapidly whirling the Alltcohols is added. whereby the mixture is whirled around until until the rubber is completely dispersed. Part 2 is then under vigorous stirring mixed into Part 1 to make a uniform, transparent gel is obtained. The presence of the alcohol facilitates complete dispersion of the gum @ is and a proper mixing of the gum with the water, part 3 is thereby prepared by dissolving the surfactant in water and then Fibred paper pulp is stirred in, so that a dispersion of the pulp is obtained in the solution.'Venn the pulp is dispersed in the solution, is Part 3 of the fish-part 1 and 2 added, whereupon the combined ingredients be mixed with each other until the mixture is homogeneous and smooth.

This mixture can be packaged in a suitable painter and immediately to promote consumer use as a face mask applied to the skin. It can e.g. B. in the form of a thin film over the entire face and neck the person to be treated, leaving out the vicinity of the eyes becomes what you get it on Dry for 10 to 2C minutes. While This drying time causes the evaporation of the liquids, especially the alcohol, has a cooling and warming effect on the skin, which is refreshing is.

When drying, the vase shrinks, so that # a tightening of the whole treated skin areas is reached.

When the mask is dry, it will separate from the skin due to the Presence of the non-ionic, õthoxylated surfactant and also due to the presence of the fibrous material in the movement of the areas of skin located under the mask, so that the mask after some time Can be removed in large sections @ By rinsing with a washcloth and Remnants of the mask are removed when the water is cool. The face is then refreshed clean and stimulated.
